Product details
Overview
TLP170AM(TPL,E from Toshiba Electronic Devices & Storage Corporation is a halogen-free, normally-open photorelay in a 4-pin SO6 (11-4M1S) package, integrating an infrared LED and photo-MOSFET. It delivers 700 mA max ON-state current, 0.3 Ω max ON-resistance, and 3750 Vrms isolation-designed for high-current On/Off control in PLC I/O modules and mechanical relay replacements.
For engineers reviewing the TLP170AM(TPL,E datasheet, TLP170AM(TPL,E pinout, TLP170AM(TPL,E application, or TLP170AM(TPL,E equivalent, key selection criteria include OFF-state voltage rating (60 V min), trigger LED current (1 mA max), thermal derating of output current, and VDE-compliant variants for safety-critical industrial interfaces.
Technical Context
The TLP170AM(TPL,E implements a single-pole, normally-open (1-Form-A) solid-state switch architecture using optically coupled GaAs LED and silicon MOSFET. Its internal two-terminal configuration shorts pins 1&3 (LED anode/cathode pair) and pins 4&6 (MOSFET drain terminals), enabling bidirectional load switching with galvanic isolation.
It operates within –40°C to +85°C ambient, supports up to 48 V supply voltage, and exhibits 3 ms typical turn-on time and 0.4 ms typical turn-off time at 20 V, 2 mA LED drive-optimized for low-power control of resistive and inductive loads in factory automation and security system I/O stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 3750 Vrms min - meets UL 1577, CSA 5A, and EN 60747-5-5 (with V4 option) for reinforced insulation in industrial control systems |
| ON-State Current | 700 mA max - supports direct switching of solenoids, indicator lamps, and small motors without external drivers |
| ON-Resistance | 0.3 Ω max - limits conduction loss to ≤147 mW at 700 mA, reducing thermal stress in compact PCB layouts |
| Trigger LED Current | 1 mA max - enables direct interface with low-drive MCU GPIOs or logic buffers without series resistor recalculations |
| OFF-State Voltage | 60 V min - sustains transient overvoltage in 24 V DC control circuits and withstands back-EMF from inductive loads |
| Turn-On/Off Time | 6 ms / 1 ms max - ensures deterministic timing for synchronized I/O scanning in PLC scan cycles |
| Creepage/Clearance | 5.0 mm min - satisfies IPC-2221B spacing requirements for Pollution Degree 2 environments |
Pinout & Package
Package: 4-pin SO6 (TOSHIBA designation 11-4M1S), surface-mount, halogen-free epoxy resin, 0.1 g typical weight, 5.0 mm creepage/clearance, 0.2 mm internal isolation thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 & 3 (shorted) | LED Anode & Cathode | Input side: bidirectional LED connection; requires series current-limiting resistor referenced to control logic rail |
| 4 & 6 (shorted) | MOSFET Drain | Output side: dual-drain configuration provides symmetrical current path for AC/DC load switching |
Key Features
| Feature | Design Value |
|---|---|
| Normally-open (1-Form-A) topology | Ensures fail-safe de-energization of connected loads during LED open-circuit or power loss |
| Halogen-free packaging | Complies with IEC 61249-2-21 and JEDEC J-STD-020 for lead-free reflow compatibility and RoHS alignment |
| Low trigger threshold (1 mA max) | Reduces MCU I/O loading and eliminates need for dedicated LED driver ICs in space-constrained designs |
| High isolation reliability | 3750 Vrms withstand and ≥10¹⁰ Ω isolation resistance enable use in SELV and functional insulation barriers per IEC 61800-5-1 |
| VDE-certifiable variant | V4 option satisfies EN 60747-5-5 for applications requiring certified safety isolation in EU machinery directives |
Applications
| Security Systems | Factory Automation (FA) |
|---|---|
Use Scenario: Isolated door lock actuation and alarm zone monitoring in access control panels. IC Role / Device Role / Timing Role: Solid-state relay replacing electromechanical contacts to eliminate bounce, wear, and EMI in 12–24 V DC lock circuits.

IC Role / Device Role / Timing Role: Output stage isolator providing galvanic separation between controller logic and 24 V DC field power. Use Value: 1 mA max trigger current simplifies interface with FPGA or ASIC I/O banks; 6 ms max turn-on ensures deterministic response within 10 ms scan cycles. |
| Measuring Instruments | I/O Interface Boards |
Use Scenario: Range switching and signal path selection in multimeters and data acquisition front-ends. IC Role / Device Role / Timing Role: Precision analog switch isolator routing test signals while blocking common-mode noise from measurement circuits. Use Value: 0.3 Ω max RON introduces <0.1% gain error at 100 mA; 100 pF max output capacitance preserves bandwidth in 100 kHz signal paths. | Use Scenario: Isolated digital input/output expansion for embedded controllers in industrial gateways. IC Role / Device Role / Timing Role: Bidirectional level-shifting and fault-isolation barrier between host processor and field-side peripherals. Use Value: Dual-drain (pins 4&6) configuration allows shared return path design; SO6 footprint minimizes board area vs. through-hole relays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PVG612A | Higher 1.2 A max ION, but 0.5 Ω max RON; 5000 Vrms isolation; 6-pin DIP package | Requires larger PCB area; better suited for higher-current 48 V systems with stricter leakage requirements | Select PVG612A when >700 mA load current or >5000 Vrms isolation is mandatory; not drop-in due to pin count and layout change |
| TLP3547 | Same SO6 package; 600 mA max ION, 0.4 Ω max RON; 5000 Vrms isolation; VDE-certified standard version | Lower current rating; tighter RON tolerance; pre-certified for EN 60747-5-5 without V4 option | Choose TLP3547 if VDE compliance is required out-of-box and 600 mA suffices; same footprint enables layout reuse |
Compared with PVG612A and TLP3547, the TLP170AM(TPL,E offers optimal balance of 700 mA current drive, ultra-low 0.3 Ω RON, and compact SO6 footprint-making it preferred for cost-sensitive, space-constrained 24 V industrial I/O where VDE certification is optional.

FAQ
What is the maximum continuous ON-state current rating for the TLP170AM(TPL,E?
The TLP170AM(TPL,E has a maximum continuous ON-state current rating of 700 mA at Ta = 25°C. Derating applies above 25°C: –8.3 mA/°C. This rating enables direct driving of solenoids, lamps, and small actuators without external amplification, provided heatsinking and PCB copper area meet thermal guidelines in the Toshiba Semiconductor Reliability Handbook.
Does the TLP170AM(TPL,E support AC load switching?
Yes, the TLP170AM(TPL,E supports AC load switching because its output consists of back-to-back MOSFETs configured as a bidirectional switch (pins 4 and 6 shorted). The 60 V minimum OFF-state voltage and 0.3 Ω max ON-resistance allow safe operation with 24 V AC control signals and resistive/inductive AC loads up to the 700 mA current limit.
What is the pin configuration and internal connection of the TLP170AM(TPL,E?
The TLP170AM(TPL,E uses a 4-pin SO6 package (11-4M1S) with internal shorting: pins 1 and 3 form the LED anode–cathode pair, while pins 4 and 6 are internally connected as the MOSFET drain terminals. This two-terminal structure simplifies PCB layout and enables symmetrical current flow in either direction across the output.
Is the TLP170AM(TPL,E halogen-free and RoHS compliant?
Yes, the TLP170AM(TPL,E is halogen-free per Toshiba's definition (Br/Cl/Sb ≤ 0.09 wt%, total Br+Cl ≤ 0.15 wt%) and RoHS compliant (Directive 2011/65/EU). The "E" suffix in the part number explicitly denotes RoHS-compatibility; full compliance documentation is available in Toshiba's environmental reports and material declarations for TLP170AM(TPL,E.
What safety certifications does the TLP170AM(TPL,E hold?
The TLP170AM(TPL,E is UL-recognized (UL 1577, File No. E67349) and cUL-recognized (CSA 5A, File No. E67349). For VDE certification to EN 60747-5-5, the V4 option variant (e.g., TLP170AM(V4,E) must be selected-the base TLP170AM(TPL,E does not carry VDE approval.
